What is it?

Counting in Sixes means adding the number 6 repeatedly to get the next number in a sequence. It's like taking a 'jump' of 6 units each time. This helps us quickly find numbers that are multiples of 6.

Simple Example

Quick Example

Imagine you are buying ladoos for a festival, and each box has 6 ladoos. If you buy 1 box, you have 6 ladoos. If you buy 2 boxes, you have 6 + 6 = 12 ladoos. For 3 boxes, you have 12 + 6 = 18 ladoos. You are counting in sixes to find the total.

Worked Example

Step-by-Step

Let's count in sixes starting from 0, up to 30.

Step 1: Start with the first number, which is 0.

---Step 2: Add 6 to the starting number: 0 + 6 = 6.

---Step 3: Add 6 to the previous result: 6 + 6 = 12.

---Step 4: Add 6 to the previous result: 12 + 6 = 18.

---Step 5: Add 6 to the previous result: 18 + 6 = 24.

---Step 6: Add 6 to the previous result: 24 + 6 = 30.

Answer: The sequence counting in sixes from 0 to 30 is 0, 6, 12, 18, 24, 30.

Why It Matters

Counting in sixes is a basic skill that helps you understand multiplication and division. It's useful in careers like engineering for calculating gears, or in finance for understanding patterns in investments. Even game developers use such patterns for level design!

Common Mistakes

MISTAKE: Students sometimes add a different number instead of 6, like adding 5 or 7. | CORRECTION: Always remember to add exactly 6 to the previous number when counting in sixes.

MISTAKE: Forgetting the starting number or not including it in the sequence. | CORRECTION: Always start from the given number (usually 0 or 6) and then add 6 repeatedly.

MISTAKE: Making calculation errors when adding 6, especially with larger numbers. | CORRECTION: Practice your addition skills regularly and double-check your sums to ensure accuracy.

Practice Questions

Try It Yourself

QUESTION: Start from 6 and count in sixes five times. What is the last number you get? | ANSWER: 36 (6, 12, 18, 24, 30, 36)

QUESTION: If a tailor uses 6 buttons for one shirt, how many buttons will he use for 7 shirts? | ANSWER: 42 buttons (6 x 7 = 42, or counting in sixes 7 times: 6, 12, 18, 24, 30, 36, 42)

QUESTION: A bus leaves a stop every 6 minutes. If the first bus left at 8:00 AM, at what time will the 5th bus leave? | ANSWER: 8:24 AM (8:00, 8:06, 8:12, 8:18, 8:24)

MCQ

Quick Quiz

Which of these sequences shows counting in sixes?

3, 6, 9, 12, 15

6, 12, 18, 24, 30

5, 10, 15, 20, 25

1, 7, 13, 19, 25

The Correct Answer Is:

Option B (6, 12, 18, 24, 30) correctly shows counting in sixes because each number is obtained by adding 6 to the previous number. Other options add 3, 5, or start with 1 and add 6.

Real World Connection

In the Real World

In India, counting in sixes is useful when you think about overs in cricket. Each over has 6 balls. So, after 1 over, 6 balls are bowled; after 2 overs, 12 balls are bowled, and so on. This helps commentators and fans quickly track the number of balls.
